INCR

Increment R

Syntax:

INCR R, d

Operands:

 R  0x6F

 [0,1]

Operation:

R + 1  dest

Status Affected:

Description:

The contents of register ‘R’ are increment. If ‘d’ is 0 the result is placed in the ACC register.

If ‘d’ is 1 the result is stored back in register ‘R’.

Cycles:

INCRSZ

Increment R, Skip if 0

Syntax:

INCRSZ R, d

Operands:

 R  0x6F

 [0,1]

Operation:

R + 1  dest, skip if result = 0

Status Affected:

None

Description:

The contents of register ‘R’ are increment. If ‘d’ is 0 the result is placed in the ACC register.

If ‘d’ is the result is stored back in register ‘R’.

If the result is 0, then the next instruction, which is already fetched, is discarded and a NOP

is executed instead and making it a two-cycle instruction.

Cycles:

1/2

IORAR

OR ACC with R

Syntax:

IORAR R, d

Operands:

 R  0x6F

 [0,1]

Operation:

ACC or R  dest

Status Affected:

Description:

Inclusive OR the ACC register with register ‘R’. If ‘d’ is 0 the result is placed in the ACC

Cycles:

IORIA

OR Immediate with ACC

Syntax:

IORIA I

Operands:

 I  0xFF

Operation:

ACC or I  ACC

Status Affected:

Description:

The contents of the ACC register are OR’ed with the 8-bit immediate ‘I’. The result is placed

in the ACC register.

Cycles:

MOVAR

Move ACC to R

Syntax:

MOVAR R

Operands:

 R  0x6F

Operation:

ACC  R

Status Affected:

None

Description:

Move data from the ACC register to register ‘R’.

Cycles:
